Ass play. It can be fun, or it can be painful. Of course, for a seriously submissive slave, pain IS pleasure. And his ass is a prime source of both pain and pleasure. In this movie, a slave receives a proper reaming up the butt with his Mistress's big black dildo. How badly does it hurt him? We can only leave that to your imagination, but a dildo of that size sliding up a slave's nether regions, no matter how well used his turd tunnel is, has to be beyond merely slightly uncomfortable. After she finally removes the dildo from his ass, Mistress then demands he kiss it!
